How can i remove flour gold from fine dirt and clay
« on: October 07, 2011, 20:29 »
Hi all
I was recently granted access to a area with an old gold wash plant on it  with lots and lots of silt around it, The silt is made up of really fine dirt ( the host rock, schist) when the dirt is dry it is like powder there is also very fine iron stone and clay mixed in. Most importantly there is heaps of flour gold in it. I know that i have to paddle or puddle the dirt to remove the clay. I tried to pan this silt and i wore a jeweler's magnifier glasses. Some gold would stick to the bottom of the pan and some would float (i know that ultra fine gold will float). But some would wash away with the silt, could the gold that washes away really be mica it's way too fine to rub between your fingers. I have a set of sieves that go down to 100 minus should i purchase a minus 150 sieve i don't want to use acid but this could be a last resort
O yes i have found a few sub-half grammers in a twenty litter bucket of dirt i could still pick them out with my fingers.
Has anyone got an idea? any help Will be very appreseated
One more question How do i get the yellow faces above in with with my letter???????

Looks like you worked out the smileys.They dont show till you post.Cannot help with panning as i detect only.Plenty of people here that will have advice. Look in Resources for GPAA ,they are big on panning and sluicing,i think many thousands of members on their forum.

           Try using magnet to remove iron stone,  Have you tried making up a small sluice with small riffles using your garden hose as a water supply.

    i Have not tried this but have read up on it
    "HOW TO REMOVE FLOUR GOLD FROM BLACK SANDS"
    Mix salt and black sand 50/50   Heat mixture to very, very,very hot
    Then dunk salt/sand in cold water    Gold will separate
    I just don't have any black sand at the moment, but as soon as I do will be giving it a go
                 Good Luck   Pyrites Pete

    If you are floating gold out of the pan makesure there is no oil fat or grease anywhere in on or around you panning gear and you could also try a little bit of detergent to break the surface tension and drop the gold to the bottom.

    Get on youtube and serch how to pan for gold its not as silly as it sounds I did and completley changed the way I looked at panning.
